I think Federer has realised he has to start being more aggressive by attacking the net because he can't hit people off the court anymore - especially guys like Rafael Nadal, Novak Djokovic and now Murray. They're too fast, they move too well.

This is a huge moment for Federer. I was one of those critics who maybe thought the days of him winning Grand Slams were over.

After this, I would say he's going to win more Grand Slams, many more, if he continues to play with the kind of passion he has now.

It was an unbelievable performance against Murray and I'm now 100% convinced he will break Pete Sampras's record.

Murray had a great tournament but I think the whole occasion was a bit too much for him in the final.

After a tough semi-final against Nadal, he needed to play the best tennis of his career against Federer and he just couldn't do it.

Nadal was flat in the semi-final. He doesn't really like the courts at Flushing Meadows and Murray disposed of him very well.

But Federer is something else. He just seems to play that much better in New York than almost anywhere else in the world.

People have been saying his best days are behind him. To be fair, that's probably true but he still played very, very good tennis throughout the tournament and he was just so determined to win.

With his experience, attitude and game plan, it was always going to be tough for Murray.

The Briton had to play at his best and serve at his best, and he didn't do that.

Federer - aside from a tricky time in the second set - just bludgeoned him.

Murray has broken through though. He has shown himself as a real threat to the top three in the world.

I think there's still a little gap between the top three and the rest, but Andy deserves to be number four, no doubt about that.

It's not inevitable that Andy will win a Grand Slam but it's definitely not impossible because nothing is impossible for Andy Murray right now.

Andy is very talented and that gives him a big edge over the majority of tennis players all over the world, he's right up there.

He has desire and a vision of what he wants but he's also grown a lot in terms of maturity - we've seen that every month and every year.

In my opinion there is no formula, the LTA is there to assist and provide us much help as possible, but ultimately it is the players who have the keys to success.

Andy made the decision to get people around him to make him fit and prevent injuries and that has been a key element in his success this year.

What has happened in the last fortnight has been great and it's not going to be the last time this happens to Andy, I'm pretty sure of that.

Even though he lost, I still expect Murray to get a beautiful reception back in the UK and inspire a lot of kids to start playing the game.

He did a great job in the final, but Federer was just too good.

You could see Murray was despondent afterwards. His expectations were high. They needed to be.

He went out there, gave it a good try, and he never quit. He was a class act and he lost to one of the best players of all time.

He had a great run to the final and not many people who start playing the game manage even that.
